£12 FLORA INDIOA. \Lardizabale<z. persistentibw vestiti. Folia alterna, digitata vel pinnata, exsftpulata, foliolis ariiculatis. Inflorescentia racemose racemis axillaribus vel ter- minalibus interdum corymbosis. Mores \albi mridescentes vel purpurei. Eructus pulposus, edulis. This small but curious group was originally indicated as a distinct Order by Brown, and has been admirably illustrated by Secaisne in » paper published in the * Archives du MuseV in 1837, since which time no addition has been made to our know- ledge of the Order. ^Lardizafralea are quite intermediate between Menispermacea and Berberidea, but possess in common a number of striking characters, which en- title them to be regarded as a yery distinct family. In the number and arrangement of the parts of the perianth the flowers agree with both Orders; but their form, and especially the shape of the stamens, which are often monadelphous, and have elon- gated anthers, readily distinguish them from both. The polyspermbus firait is also a peculiar character, shared only by PodopJtyttum amongst Berberidea. The abnormal arrangement of the ovules over the whole surface of the ovary was formerly consi- dered a universal distinguishing mark, but in Decaisneatbe ordinary type reappears. In the unisexual flowers and scandent habit of the majority of the Order, Lardiza- bdlea agree with Menispermacetf, but the indefinite ovules and the whole structure of the androeciuru at once distinguish them, and compound leaves do not occur in Menisperotacea, except in the imperfectly known genus Bnrasaia,\which, as we have already mentioned, is in that respect quite intermediate, but seems to have the em- bryo of Menisperinacea. To Ber&eridea they approach through Lardizafato, which has flowers and leaves more like those of a Berberry than those of the Asiatic genera of the Order, and especially through Decaisuea, which has the simply pinnated leaves, and leaflets articulating with the petiole, of the section Malionia, and through Podoftyllum, which has a fleshy pericarp, broad placenta, and the seeds imbedded in pulp. The solitary carpels of Berlwridea> however, at once distinguish them. The number of species known is very small, and, except two, which are natives of western South America, T>eyond the tropic, the group is entirely confined to the Himalayo-Chinese region, the species occurring throughout the Himalaya and in the Khasia, and1"^ the hilly regions of China and of Japan. None are known in Ava, in the Malayan Peniusula, or in the Indian Archipelago. 1. DECAISNEA, H.f. et T. Sepala 6, lineari-subulata, aest. subimbricantia. Pefala 0.

This remarkable genus wakes a very unexpected and valuable addition to our know- ledge of the Natural Order to which it belongs, and will therefore most appropriately have the name of M. Decaisne*, in whose admirable monograph we have a model of * Two Orchideoua genera have already been dedicated to M. Decaisne, one by Brongmart, the other-by liudleyj but, by an unfortunate mischance, in both cases u previous name supersedes tliat of Decaisnea.
